Displaying process limits

You can use any of the following to display process limits:

ps shell command
ulimit shell command
D OMVS,LIMIT operator command
D OMVS,OPTIONS
MEMLIMIT
ASSIZEMAX

You can display the RACF® limit using the following RACF command:

LU user NORACF OMVS

For more information about how to obtain security information for users, see Obtaining security information about users. You can obtain the information if the security administrator has set up field-level access for users for the OMVS segment of the RACF user profile as described in Setting up field-level access for the OMVS segment of a user profile.

Example: Issue:

ps

Result: Following is a sample output:

/shut/home/wellie2==>ps  ; alias to ps -o ruser,pid,vsz,vsz64,vszlmt64,comm

   Erin  29 2432  0     20M /tst/bin/ps -oruser,pid,vsz,vsz64,vszlmt64 -oargs

Example: Issue:

ulimit -a

Result: Following is a sample output:

Example: Assuming that the PID is 0050331651:

d omvs,limits,pid=0050331651

Result: Following is a sample output:
